Worksheet: Chemical Potentials in Mixtures

In this worksheet, we will practice using the Gibbs–Duhem equation to calculate the chemical potentials of species in an equilibrium mixture.

Q1:

The equilibrium vapor pressure of water at
298 K
is 32×10 bar.
Is the chemical potential of HO()2l at
298 K
and 2.7×10 bar
less than, equal to, or greater than the chemical potential of HO()2g
at the same temperature
and pressure?
